stl vs OrbitCAD

stl-er is the world's first AI-powered 3D model generator built for 3D printing. Simply describe any object in plain text — and get a fully parametric, functional 3D model in seconds. No CAD experience needed. HOW IT WORKS 1. Describe what you want (e.g., "phone stand with cable slot") 2. AI generates a precise 3D model using CAD 3. Adjust dimensions with live parameter sliders 4. Download the STL file — ready for your 3D printer KEY FEATURES • AI-Powered Generation — From text prompt to 3D model in seconds • Live Parameter Sliders — Fine-tune dimensions, rounding, and details in real-time • AI Refinement — Modify designs with follow-up prompts ("make it taller", "add ventilation holes") • Instant STL Downloads — Export files ready for any 3D printer or slicer • 3D Preview — Rotate and inspect your model before downloading • Community Library — Browse, remix, and share models created by other makers • Cross-Platform — Seamlessly sync between iPhone, iPad, and Web PERFECT FOR • 3D printing enthusiasts and makers • DIY builders and hobbyists • Product designers and engineers • Educators and students • Anyone who wants custom 3D models without learning CAD software WHY stl-er? Traditional CAD software has a steep learning curve. AI model generators produce meshes that aren't optimized for printing. stl-er combines the precision of parametric CAD with the simplicity of natural language — every model is mathematically exact, fully customizable, and ready to print. Every design is solid, manifold, and slicer-ready. Start creating. Now. Terms of Use: https://www.stl-er.com/terms-conditions/ Privacy Policy: https://www.stl-er.com/privacy-policy/

OrbitCAD turns plain-English descriptions into real, engineering-grade mechanical parts — no CAD training required. Just describe what you need: "spur gear, module 2, 24 teeth" or "arm joint, 40mm bore" — and OrbitCAD generates accurate, parametric 3D geometry in seconds. Rotate, inspect, and export it as STEP or STL for 3D printing or professional CAD workflows. WHAT YOU CAN DESIGN - Gears — spur, helical, bevel, worm - Planetary gearboxes - Shafts, couplings, and drive components - Robotics parts — arm joints, mounts, and more - Drone propellers and custom blade geometry - And an expanding library of mechanical components BUILT FOR REAL ENGINEERING Every part is generated with accurate dimensions, correct tooth profiles, and proper mechanical relationships — not approximations. Inspect wall thickness, diameters, and tolerances directly in the app before you export. EXPORT READY Download STEP files for professional CAD software, or STL for 3D printing — straight from your phone. Whether you're prototyping a robotics project, need a quick replacement part, or just want to explore mechanical design without opening a full CAD suite, OrbitCAD gets you from idea to exportable geometry in one conversation.
